SPECIFICATION forming part; of Letters Patent No. 334,874, dated January 26, 1886.

Application filed May 20, 1885. Serial No. 166,194.

To all whom it may concern.-

Be it known that I, JOSEPH M. LANGSTON, of Berlin, inthe county of Sangamon and State of Illinois, have invented a new and Improved Draft-Equalizer, of which the following is a full, clear, and exact description.

The object of my invent-ion is to provide a new and improved draft-equalizer for fourhorse teams, which equalizer is so constructed that an equal amount of the load is drawn by each animal.

The invention consists in certain improve- Patent No. 253,071 of the United States were granted to me on the 31st of January, 1882, as Will be hereinafter fully described, and specifically pointed out in the claim. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved draft-equalizer. Fig. 2 is a front view of the same. Fig. 3 is a front view of a modification of the same.

The levers A are pivoted on the top of the double-tree B, at the ends of the same, and on the outer end of each lever Aa single-tree, O, is held. The inner ends of the levers A are each connected with links D, secured to a ring, E, with which the lead-rod F is connected. Above the double'tree B a metal bar, G, is placed,which is held by the end pins, H, passed through the levers A, and by a central pin, J, the head of which is in a depression, K, in the (N0 model middle of the said bar. By forming the bar G with the depression K a seat for the head of the bolt is provided, thus taking it out of the way, and the walls of the depression or recess prevent the head of the bolt from turning, thus making it impossible for the bolt to work loose. A further advantage of the depression is that it brings the points or parts against which the bolt rests nearer together, as the bottom of the depression through which the bolt passes is of course nearer to the doubletree than the central part of a straight bar could be. A clevis, L, is held by the central pin, J, and projects from the rear of the doubletree. \Vashers M are placed between the top surfaces of the levers A and the bar G. When the drafteqnalizer is to be used for a single team, the inner ends are connected by a link, N, as shown in Fig. 3.

By using the above-described equalizer the load is distributed equally among the animals of draft.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The combination, with the double tree B, of the levers A, pivoted 'on the ends of the same, the single-trees O on the outer ends of the levers A, the metal bar-G, having a depression, K, and of the bolt J, the head of which is in said depression, substantially as herein shown and described.
